Icon and Comment count not updating

I have Receipt and Comment model. When a new receipt is created the “has_notes” column in the Receipt model should display an icon “heroicon-o-document-arrow-up” and comment count of 0. Once the receipt record is created a user can then go in and add a note which is saved to the Comment model and the Receipt model should display an icon “heroicon-o-document” and comment should increment up.

In Filament 3 / Laravel 11 I have created the Receipt Resource and a CommentsRelationManager but cannot get the icon to change or the comment count to increment once a note is present in the record? Can anyone suggest a solution to this?

The CommentsRelationManager

// app/Filament/Resources/ReceiptResource/RelationManagers/CommentsRelationManager.php

namespace App\Filament\Resources\ReceiptResource\RelationManagers;

use Filament\Forms;
use Filament\Resources\Form;
use Filament\Resources\RelationManagers\RelationManager;
use Filament\Tables;
use Filament\Tables\Columns\TextColumn;
use Illuminate\Database\Eloquent\Model;

class CommentsRelationManager extends RelationManager
{
    protected static string $relationship = 'comments';
    protected static ?string $recordTitleAttribute = 'comment';

    public static function form(Form $form): Form
    {
        return $form
            ->schema([
                Forms\Components\Textarea::make('comment')
                    ->required()
                    ->label('Comment'),
            ]);
    }

    public static function table(Table $table): Table
    {
        return $table
            ->columns([
                TextColumn::make('comment')->label('Comment'),
                TextColumn::make('created_at')->label('Created At')->dateTime(),
            ])
            ->filters([
                //
            ])
            ->headerActions([
                Tables\Actions\CreateAction::make(),
            ])
            ->actions([
                Tables\Actions\EditAction::make(),
                Tables\Actions\DeleteAction::make(),
            ]);
    }

                    ->schema([

                            ->hiddenOn(['create', 'edit']),
                    ]),
            ]);
    }

    public static function table(Table $table): Table

            ->persistFiltersInSession()
            ->filtersTriggerAction(function ($action) {
                return $action->button()->label('Filters');
            })
            ->columns([
